Retinol for men: the no-nonsense guide (myths, percentages and week-by-week results)
The short answer
Retinol is vitamin A, and it's the anti-ageing ingredient with the most clinical research behind it: it speeds up skin renewal and gets your skin producing collagen the way it did when you were 20. It works on wrinkles and fine lines, but also on acne, pores, shine, dark spots and texture. It's effective from 0.1%, and the legal maximum for facial cosmetics in the EU is 0.3% (exactly what WowYoung contains). Use it at night, on clean, dry skin, starting with 2 nights in week one and building up to daily by week four. The first changes show up after a month, they're obvious by the second and undeniable by the third. The redness in the first couple of weeks is called retinisation and it passes. During the day, sunscreen.
Let us guess…
You spotted a couple of fine lines in the mirror. You went to Google (or asked an AI) for help. You started reading about anti-ageing creams with retinol… and came away with more fears and doubts than facts 🤔
Fair enough: retinol is the most studied anti-ageing ingredient in the history of cosmetics and, at the same time, the one dragging around the most tall tales. That it burns. That you can't use it in summer. That bakuchiol is the same thing but natural. That you have to wait a year.
So we've put everything we've been saying about retinol for years in one place: what it is, why it suits blokes especially well, what percentage you actually need, how to start without turning into a lobster and what you'll see in the mirror week by week.
As always: plain and simple. Then you make your own calls and put whatever you fancy on your face.

What is retinol?
Retinol (or vitamin A) is one of the most studied, most trialled and most proven anti-ageing ingredients in the whole history of cosmetics (which, granted, isn't that long, but still).
Vitamin A has been known about for ages, but it only started being used dermatologically in the 1960s. And the funny part is that it was discovered completely by accident: they were testing anti-acne products and, as luck would have it, noticed that patients' wrinkles were softening along with their spots… so they connected the dots, and here we are.
Translation: it's the only family of actives with extensive, independent, objective scientific literature behind it for treating wrinkles and expression lines. Every other anti-ageing ingredient is playing in a different league.
Is retinol only good for wrinkles? FALSE
The end result of retinol is skin with fewer wrinkles that looks smoother, firmer and tighter. But its real trick, put simply, is acting like a personal trainer that puts your skin's factory back to work so it regenerates and churns out the things you lose with age: collagen mainly, but also proteins and natural moisturising factors.
That's why retinol thickens the epidermis, slows photo-ageing and softens fine lines. But on top of that, thanks to its knack for kick-starting cell regeneration Wolverine-style, it's also brilliant against:
- Acne and clogged pores
- Shine and excess sebum
- Blackheads
- Dark spots, freckles, melasma and hyperpigmentation
- Scars from the acne you had as a teenager
An absolute weapon in a bottle.
Why do men need retinol (even more)?
Skin is skin and gender doesn't come into it… we know. But there are a few quirks of 'typical' male skin that make retinol especially useful for us:
1. Oilier skin, with shine and blackheads
Statistically, blokes have oilier skin. #FACTs. That brings more visible pores, blackheads and the 7pm shine. Retinol helps by balancing sebum production and making pores less noticeable.
2. Thicker skin, with acne scars and ingrown hairs
Thick skin + beard = ingrown hairs when you shave, spots and blemishes that leave you more scarred than your ex did. Retinol speeds up the cycle of producing new skin and shedding the old 🐍, so nothing sits under the surface for long.
3. Forgiving skin that we never protect
Because our skin is oily and thick we protect it less from the sun, since we don't notice the damage as much up front. Mistake. Then the wrinkles and dark spots turn up far deeper because of all those years of zero caution 😅. And there's retinol again, cleaning up after past excesses.
4. Bonus: retinol and shaving get on better than you'd think
By renewing the surface layer of the skin, retinol reduces ingrown hairs and post-shave irritation over time. Just don't put them together in the same moment: shave in the morning and use retinol at night. The blade is quite enough exfoliation for one day.
What age should I start using retinol?
Friendly reminder: retinol has no age limit. The best time is now. What changes is what you'll appreciate about it depending on which decade you're in:
- In your twenties you'll love that it keeps spots, blackheads and shine in check.
- In your thirties you'll enjoy watching those first lines soften.
- In your silver fox era you'll value what it does for evening out texture and keeping skin looking smooth.
And one stat for anyone still on the fence: your skin naturally renews itself every 28 days when you're young. Your face peaks at 20 and it's downhill from there (at roughly 1% a year). By 40-50 it takes twice as long to renew. After 50, three times. Retinol is what gives you that rhythm back.
Retinol, retinal, retinyl, tretinoin: who's who
This is one of the big sources of confusion, because not everything labelled retinol is retinol. They're all vitamin A derivatives, but your skin has to convert them until it reaches retinoic acid (the genuinely active form). Fewer conversion steps means more potency… and more chance of a bit of stinging.
| Derivative | Steps to activate | Potency | Who it's for |
|---|---|---|---|
| Retinyl palmitate / propionate | 3 | The gentlest | Very reactive skin or absolute first-timers |
| Retinol | 2 | The sweet spot 👌 | The gold standard in cosmetics |
| Retinal (retinaldehyde) | 1 | Faster | Anyone with some mileage already |
| Tretinoin / retinoic acid | 0 | Maximum | Prescription only |
And then there are the lab-made molecules built from retinol (Granactive, Retinol Complex, encapsulated retinoids…), designed to diffuse into the skin more slowly or to minimise reactions. The consequence? You can't compare percentages across brands directly. A 0.5% of one thing can deliver less than a 0.3% of another.
What percentage of retinol works? (and what the law says)
It's effective from 0.1% and you'll notice the effects over the following weeks (near the eyes, with considerably less than that).
And here's what's changed and almost nobody has told you: since November 2025, the legal maximum for retinol in facial cosmetics in the European Union is 0.3% (and 0.05% in body products). It's set by Regulation (EU) 2024/996, and products already on the market at higher concentrations have until May 2027 to be reformulated or withdrawn. On top of that, bottles have to carry a warning that they contain vitamin A.
Don't panic: it isn't because retinol is dangerous. It's a precautionary measure, to stop you exceeding your daily vitamin A intake by stacking creams, supplements and food. If you need more than that percentage, it's possible and it's safe, but you'll have to see a doctor for a prescription first.
So if you spot a "1% retinol" in an over-the-counter cosmetic, that's a red flag: either it isn't pure retinol, or it shouldn't be on the shelf.
And a third classic trap: because retinol is a seriously expensive ingredient, some brands prefer to put "with retinol", "pro-retinol" or "retinol-like" on the label without ever explaining the %... all sizzle and no steak.
At Siwon we say it plainly: WowYoung contains 0.3% retinol. The maximum the law allows. Not a decimal less.
How to work retinol in without turning into a lobster
Like going back to the gym in September after a summer of excess: the smart move is a warm-up and acclimatisation phase so you don't end up aching.
This is the progression we recommend to anyone starting out, and it works with any retinol cream, ours or not:
- Week 1 · Two nights. A Monday and a Thursday, say. That's it. Even if you get no reaction at all, resist the urge to speed up.
- Week 2 · Three nights. Monday, Wednesday and Friday. This is usually where a bit of tightness shows up: normal, and a good sign.
- Week 3 · Every other night. You're nearly at cruising speed.
- Week 4 onwards · Every night. Congratulations, you can now give your face the full treatment without worrying.
The beginner's 5 commandments
At night
So it can work through all those hours you spend asleep, without you washing it off, touching it or rubbing it away.
Clean, dry face
No dirt and no water in the mix. On damp skin it penetrates more than it should and the irritation multiplies.
Go easy on the amount
2-3 pumps, spread out. More product isn't more result: it's more redness and less bottle.
Mind the delicate bits
Eye contour, neck and the corners of the mouth are off limits at first. Work them in as the weeks go by.
Never straight after shaving
Shave in the morning and save the retinol for the night. Freshly shaved skin has had quite enough already.
And the sixth, which wouldn't fit: pair it with your go-to moisturiser — like the hyaluronic acid in our Dragon Shot — for the first few days, to head off dryness.
What you'll see in the mirror, week by week
Because it's the same thing you'd expect to be told when you join a gym, when you pay a nutritionist, or when you're about to book that flight to Istanbul 👨🏽🦲.

Day 0
Take the selfie
Like any self-respecting gym poser, step one is a proper close-up selfie, the kind that will never leave your phone. That way you can compare month by month. And remember the golden rule: whatever you put in today fully surfaces in 28 days. Warm up, you're on!
-
First week
Better texture and tone overall
For the first 3-10 days retinol is sending the first signals to your cells to ramp up the good-stuff factory (fibroblasts, collagen…), but there hasn't been time for any of it to surface yet.
What you will notice when you touch your face: it feels softer and more "switched on". (People tend to use words like radiant, glowing or luminous… but that just makes us picture grease, and that's not the film we're in. Think more like the flush you get after exercise or sex.)
On the "bad" side: these are peak aching days. It's like taking someone who hasn't done ANY exercise in 10 years and putting them through 7 CrossFit sessions in week one. Hence: slowly does it.
-
First month
Results you can see up close
You've completed your first renewal cycle and the 21 days people reckon it takes to build a habit. This is also when you can start using it on the areas you skipped: ears, neck, the corners of your mouth and closer to the eye contour.
Compare it to the day zero photo and you'll see slightly finer lines and smoother skin overall. From here the layers of new, elastic skin start stacking up underneath, and the visual effect becomes exponential.
Watch out for the purge: in these weeks it's common to get a few more spots than usual. That's because the new cells have made the full 28-day journey, shoving the old layers along like a packed Tube carriage, and everything that was sitting under the surface has come up all at once. It doesn't mean it disagrees with you: it means it's working.
-
Third month
The before/after for your IG grid
The change is obvious without anyone having to squint: silky skin, far fewer spots, blemishes and blackheads, and noticeably finer wrinkles and expression lines. If your issue was excess oil, you'll notice your face is less shiny by the end of the day.
The factory is running flat out: the layers of young cells are thick again and the old skin layers are thinner. As a bonus, sun spots and scars from teenage acne will have turned the volume down too.
-
First anniversary
Eternal fit daddy
Results stack up with every 28-day cycle and after a year you'll be amazed (and so will everyone else) at how far you've wound the clock back. Fine lines are barely there and the deeper expression ones (the laughing ones, the annoyed ones) show far less, without you losing any character.
The good news? Keep showing up at the retinol gym and you keep the results. And it costs you nothing, because by now you do it like brushing your teeth.
The bad news? Like exercise or eating well, it's a lifelong habit 😅. That said, it pays off in the ego, in your health and in the mirror.
What can I mix retinol with? (and what's better left alone)
Another classic question almost nobody answers clearly:
| Ingredient | Alongside retinol? | How to do it |
|---|---|---|
| Hyaluronic acid | ✅ Yes, the best ally | Before or after. Cushions the dryness of the first weeks. |
| Niacinamide | ✅ Yes | Reduces irritation. Top combo for oily skin. |
| Ceramides and moisturisers | ✅ Yes | Layer them over the retinol, no fear. |
| Sunscreen | ✅ Non-negotiable | Every morning, always. It's the other half of the anti-ageing treatment. |
| Vitamin C | ⚠️ Better apart | Vitamin C by day, retinol at night. Textbook combo. |
| AHAs / BHAs (glycolic, salicylic) | ⚠️ With care | On different nights, never together when you're starting out. |
| Benzoyl peroxide | ❌ Not at the same time | They cancel each other out and multiply irritation. One morning, one night. |
| Another retinoid | ❌ No | More isn't better. It's redder. |
The myths, one by one
"Retinol irritates and makes you peel" → FALSE (sort of)
It can happen at high concentrations, with old formulas that don't buffer the effects, or on very sensitive skin. And it's normal to feel some irritation in the first and second week: that's retinisation, or as we call it, the first-few-days gym ache, which wears off as you train.
That said, every manufacturer (us included) puts warnings out there, because we're terrified someone will post a photo online with a red face and blame us. But unless you do something daft, NOTHING is going to happen. At most, a couple of days of redness around the crow's feet, which is the most delicate area (and it's not exactly the plan to shove the cream into your eyeball either).
"You can't use retinol during the day" → FALSE
What actually happens is that retinol is photosensitive: it loses effectiveness when exposed to sunlight, so you'd be throwing money away. It isn't photosensitising (it doesn't burn your face). The fix if you want it during the day? High-factor sunscreen over the top and done. Even so, we'd rather you used it at night.
"You have to quit retinol in summer" → FALSE
In fact, if you stop completely over the summer you lose the gains you made all year and you have to start the course again in September. In that sense retinol is like the gym: it's normal to ease off for a while, but let it be because you fancy a break, not because you're scared of a particular season.
"Bakuchiol is plant-based retinol" → FALSE
There's a lot of hype around bakuchiol and the comparisons are unfair. People compare them for two reasons: 1) marketing and 2) because it looks like it might have similar effects.
Bakuchiol is an antioxidant, it slows collagen degradation, it's anti-inflammatory, it might help with acne… all lovely, except the scientific evidence for all of that is very limited and, for now, not very solid. In short, bakuchiol is an ingredient that promises, but hasn't proven yet.
And note that the vegan argument falls apart on its own: retinol doesn't have to come from animal sources. The one in our WowYoung is synthetic, so there are vegan alternatives to retinol… that are still retinol.
"The higher the percentage, the better" → FALSE
We've covered it: by law the ceiling in facial cosmetics is 0.3%, and above that you're into prescription territory. Pushing the percentage without any groundwork doesn't speed up results: it speeds up redness and the odds you'll quit within a fortnight.
"It's a women's thing" → Come off it
Skin doesn't check your ID. And on top of that, given everything above, male skin gets on with it brilliantly.
The 6 mistakes that get retinol blamed (and make people quit)
- Going daily from day one. Four days later you're red and you give up.
- Slathering it on. 2-3 pumps is plenty for the whole face.
- Applying it to damp skin. It penetrates more than it should and multiplies irritation.
- Skipping moisturiser. Retinol renews; moisturiser repairs. They work as a team.
- Ignoring sunscreen. It's 50% of the anti-ageing result. Without it you're mopping with the tap running.
- Judging it after two weeks. The first real verdict comes at one month. The good one, at three.
In short
Nobody ever told you that you can work on your health and fitness in your face too. And that seeing results and keeping them was far easier than building a six-pack at the gym, reading 20 books a year or eating green from Monday to Friday.
With retinol you need to know far less: you, your bottle, 20 seconds a day and the feeling of looking after yourself, improving and staying fit over time.
Retinol is GREAT. And used sensibly, it's safe, effective and leaves you with healthier skin within weeks.

Frequently asked questions about retinol
How long does retinol take to work?
The first signs show up at the end of the first month of continuous use. They become more obvious by the end of the second. And there's no doubt about the effects by the end of the third. The genuinely powerful part is the cumulative effect after years of use, because every 28-day cycle builds on the last.
What percentage of retinol should I use?
It's effective from 0.1%. The maximum permitted in facial cosmetics in the European Union is 0.3%, which is exactly what WowYoung contains. Above that you need a prescription. And bear in mind: percentages aren't comparable between brands if one uses pure retinol and another uses a derivative or an encapsulated molecule.
Is retinol used during the day or at night?
At night. Not because it burns your face, but because it's photosensitive: light degrades it and it loses effectiveness. If you do decide to use it during the day, pair it with high-factor sunscreen, no exceptions.
Can I use retinol if I have sensitive skin?
Yes, starting every other day until your skin adapts and pairing it with a good moisturiser. WowYoung is formulated for people starting out with retinol and includes soothing ingredients (centella asiatica, green algae, hyaluronic acid) to buffer it. If the irritation is intense or lasts more than a month, stop and see a dermatologist.
Can I use retinol if I shave every day?
Yes. Shave in the morning and use retinol at night, so you're not hitting your skin with two things at once. Over time you'll notice fewer ingrown hairs and less post-shave irritation, because retinol speeds up the renewal of the surface layer.
Do I have to stop using retinol in summer?
No. If you stop completely you lose the gains you made over the year and you have to start the course again. What can't be missing in summer is sunscreen in the morning.
What is retinisation?
It's the 1-3 week period in which your skin adapts to retinol. You may get some redness, tightness or dryness, especially around the crow's feet. It's normal and it passes. If it gets uncomfortable, stop for a couple of days and pick it up again more slowly.
Does retinol cause spots at first?
It can happen during the first month: it's what's known as the purge. The new cells push everything that was already sitting under your skin up to the surface, and it all comes out at once. It's a sign it's working, not a sign it disagrees with you.
Retinol or bakuchiol?
Retinol. Bakuchiol is a promising ingredient — antioxidant, anti-inflammatory, it slows collagen degradation — but the scientific evidence backing it today is limited and not very solid. And if your reason for looking at it is that you want something vegan, synthetic retinol is vegan too.
Can I use retinol and vitamin C together?
Better apart: vitamin C in the morning (it works beautifully under sunscreen) and retinol at night. It's not that they're incompatible, it's that each performs better in its own shift.
What age should you start using retinol?
Whenever you like: retinol has no age limit. In your twenties you'll appreciate it for spots, blackheads and shine; in your thirties, for the first expression lines; and from then on, for texture and firmness. The earlier you start, the more it works as prevention and the less as repair.
What's the difference between retinol and retinal?
Both are vitamin A derivatives, and the difference is how many steps your skin needs to convert them into retinoic acid, the active form. Retinal takes one step and retinol takes two, so retinal acts a little faster and also irritates a little more. Retinol is the gold standard in cosmetics because of its balance between effectiveness and tolerance.
So what now?
Start tonight, take your day zero photo and we'll see you in 28 days. Two nights in the first week. That's all.
